I am trying to implement a simple web service using SOAP using Node Js and node-soap, but the client side seems to have problems using the server.
assert.js:92
throw new assert.AssertionError({

AssertionError: invalid message definition for document style binding

AssertionError: invalid message definition for document style binding
any help will be really appreciated
As user672320 pointed out the reason client.js failed was because the format of the wsdl used was 'RPC/literal' but the style was set as 'document' rather than RPC.
In fact any one of five formats can be used for wsdl, each has a diferent format.
See Which style of WSDL should I use? for a discussion of which style to use.
Also, the example given is not complete.
See below for expanded version:

server.js:
/*jslint node: true */
"use strict";
var soap = require('soap');
var http = require('http');
var service = {
ws: {
calc: {
sumar : function(args) {
var n = 1*args.a + 1*args.b;
return { sumres : n };
},
multiplicar : function(args) {
var n = args.a * args.b;
return { mulres : n };
}

}
};
var xml = require('fs').readFileSync('wscalc1.wsdl', 'utf8');
var server = http.createServer(function(request,response) {
response.end("404: Not Found: "+request.url);
});
server.listen(8001);
soap.listen(server, '/wscalc1', service, xml);
client.js:
var soap = require('soap');
var url = 'http://localhost:8001/wscalc1?wsdl';
soap.createClient(url, function(err, client) {
if (err) throw err;
console.log(client.describe().ws.calc);
client.multiplicar({a: 4,b: 3},function(err,res){
if (err) throw err;
console.log(res);
});
client.sumar({a: 4,b: 3},function(err,res){
if (err) throw err;
console.log(res);
});
});
with that the code output is:
{ sumar:
{ input: { a: 'xs:string', b: 'xs:string' },
output: { sumres: 'xs:string' } },
multiplicar:
{ input: { a: 'xs:string', b: 'xs:string' },
output: { mulres: 'xs:string' } } }
{ mulres: '12' }
{ sumres: '7' }
in the wsdl file what i change is the style from document to rpc trying to get antoher response using the client.js
What i receive is this output.
{ sumar:
{ input: { a: 'xs:string', b: 'xs:string' },
output: { res: 'xs:string' } },
multiplicar:
{ input: { a: 'xs:string', b: 'xs:string' },
output: { res: 'xs:string' } } }
{ res: '2' }
